History

Prospero was a desolate, dark planet and was chosen by its inhabitants because of its distance from Terra. Mutants and Psykers lived in reclusion and study, and Magnus fit in well with this group due to his incredible psychic potential.[Needs Citation]

In the end, the only good thing about Prospero was its remoteness, which made it easy to hide on. It had one major city, Tizca, a gleaming city of white marble, with spires reaching into the sky. It was situated on the most central of the many mountains of the planet, nourished by underground hydroponics and techno-psychic collectible arrays providing sustainable energy. All the towers were gleaming and there were soaring obelisks and towering pyramids.[Needs Citation]

When Magnus arrived, he crashed into the central plaza of the city. The city was very vulnerable from attack from above, but no one seemed to notice this until Leman Russ came and bombarded the planet. He attacked the planet with extreme viciousness and devastating results, slaughtering all he could find. In the end, after a grueling duel between the two primarchs, Magnus cast spells that took all of the great city, his marines, and his precious libraries to a new Homeworld, the Planet of Sorcerers.[Needs Citation]

Later in the Heresy, the White Scars under Jaghatai Khan arrived to investigate what had transpired. They found no survivors from either side and the vengeful ghosts of slain Thousand Sons wandering the ruins of Tizca. The Khan was confronted by a shade of Magnus, who discussed both of their successes and failures and may have been tempting his brother to join the forces of Chaos. After refusing Magnus, Jaghatai then refused the newly arrived Mortarion and the two Primarch's battled as their fleets clashed in space. After a brief but intense battle between Astartes warships, the Death Guard disengaged.[3]

Ecology

At least one indigenous species on Prospero was known to have been hostile and extremely dangerous to human life. The psychneuein, a species commonly found on Prospero, was a major threat to the early settlers of Prospero and continued to present a problem to the inhabitants of the world all the way up to the end, when the planet's entire ecosystem was destroyed by planetary bombardment.[Needs Citation]

The psychneuein reproduced by implanting eggs into a host's brain psychically. An infected host would have no idea they'd been implanted until the eggs began to grow, causing severe pain and ultimately, death as the eggs hatched. On only one known occasion has a victim been successfully cured of the implanted psychic eggs. An archaeologist, living in Tizca, had been implanted while outside the city on a day trip. She later collapsed and was taken to a hospital where a team of highly skilled Thousand Sons Astartes were able to use their powers to remove the eggs from her brain in a form of psychic surgery.[2]
